SPECIFICATION forming part Of Letters Patent NO. 390,730, dated QCLO'OGI 9, 1888.

Application filed April 21, 1888. Serial No. 271.461. (Modehl To ctZZ whom it may concern.-

Be it known that I, ELIJAH WARE, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Injectors, of which the following is a specification.

This invention relates to steam injectors; and it has forits object to provide a simple and improved device of this class in which the water and steam will be brought into instant contact and the latter instantly condensed.

A further object of my invention is to provide a steam-inj ector possessing advantages in point of simplicity, inexpensiveness, durability, and general efficiency.

To this end my invention consists substantially in the details of construction hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of a steam-injector embodying my invention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a section on the line w 00, Fig. 2. Fig. 4 is a section on the line y i Fig. 2. Fig. 5 is a section on the line 2 .2, Fig. 2. Fig. 6 is a detail perspective view of the ejecting-cone.

Corresponding parts in the figures are denoted by the same letters of reference.

My present invention is designed as an improvement upon the device for which Letters Patent were granted me August 23, 1887, numbered 368,798, and preferably embodies in the main the general construction therein setforth.

Referring to the drawings, A designates a casing provided with abearing, a,within which is loosely held an ejecting-cone, -13, preferably provided with a circumferential groove, 7), for the reception of a paeking-ring. This cone has a transverse partition, 0, dividing it into two chambers, B B", said partition being provided with a centrally/disposed hole or periorod, If, which extends through the casing A and hasathumb-serew, L This rod is adapted to regulate the location of the cone in its bearing a. If desired, I may employ a series of wires or cylindrical rods, S, pointed at their ends and of different lengths. These wires or rods are located opposite the steam-ejecting tubes D D, and are adapted to enter them, one at a time, as the cone is drawn back into its bearings to lessen the supply of steam.

E designates a casing joined to the casing A at right angles thereto, and provided with an water-inlet pipe, G. Within this casing E is located a main cone, F, provided with a conical opening, the larger end of which extends over the conical walls of the chamber 13*, leaving a narrow channel,f, between. The cone F is provided near its smaller end with screwthreads engaging a central screw threaded opening, h, in the end wall, H, ofa cylinder, H, seated in a pipe, E, which is connected with the casing E. lVithin the pipe E the cone F is reduced, forming a channel, T, between it and the said pipe.

The wall H of the cylinder H is also provided with a series of openings, h, around the opening h, adapted to be closed by a valve, I, mounted upon and encircling the cone F, said tube being provided with a shoulder, f, to limit the movement of the valve.

The cylinder H is provided at its outer end with a wall,H",having acircumferential flange, h, which rests against a shoulder, e, within the pipe This wallH? is provided with a central opening, h, through which extends a delivery-tube, H. This tube projects about one-third its length within the cylinder Hand has pivoted at its outer end a valve, J.

K designates an overflowpipe parallel with the pipe E and opening into the channel T. A segmental valve, L, is located within the pipe and provided with an inwardly-projecting tube, Z, connecting with apassa-ge-way, U, which is connected with the steam-inlet pipe V, opening into the casing A. This valve is designed to close simultaneously both connections with the overflow-pipe.

The operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains. The steaminlet, water inlet, and overflow valves are 9 stereo adapted to be operated simultaneously by connections between them, and when the two former are opened the latter is closed. When the steam inlet and water inlet valves are opened, the steam passes through the steamejecting tubes D D, while the water passes through the apertures b and channelf, thus bringing the steam and water into immediate contact, and thereby instantly condensing the steam. \Vhen it is desired to decrease the steam and increase the water-supply, the cone is drawn back into its bearings by the red I)", when the wires or rods S enter the ejectingtubes one at a time and close them, while the channel f is widened, thus accomplishing the object desired. To increase the steam and decrease the water-supply,the operation is reversed.

I claim as my invention- 1. In an injector, an ejecting-cone comprising a shell, a transverse partition therein, a series of ejecting-tubes projecting from said partition, and a series of water-apertures provided through said casing near the inner ends of said tubes, substantially as and for the purpose set forth.

2. In an injector, the combination,- with a casing provided with a series of projecting wires or rods therein, of an ejecting-cone located within said casi ng, comprising a shell and a partition having a series of ejecting-tubes corresponding and adapted to engage said wires or rods, substantially as set forth.

3. In an injector, the combination, with a casing provided with a series of projecting wires or rods of different lengths, of an ad justable ejecting-cone provided with a series of ejecting-tubes corresponding and adapted to engage said wires or rods, substantially as set forth.

4. In an injector, the combination, with a casing provided with a series of projecting wires or rods, of an ejectingcone located in said casing, provided with a series of ejectingtubes corresponding and adapted to engage said wires or rods, a series of water-apertures in the cone, and an adjusting-rod for adjusting the latter, substantially as set forth.

5. In an injector, the combination, with a casing having water and steam inlet pipes and an outlct'pipe connected therewith, of an overflow-pipe connected and parallel with said outlet'pipe, and a valve located in the ovcrflow-pipe segmental in cross-section and provided with an inwardly projecting tube adapted to connect with a passageway connected with the steam-inlet valve, substantially as set forth.

(3. In an injector, the combination,with the casing, of a main cone and an ejecting-cone projecting therein, comprising a shell, a series of ejectingtubes, and a series of waterapertures in said shell, substantially as set forth.

7. In an injector, the combination, with a casing and an outlet-pipe connected therewith, of a main cone located in said casing, a cylinder located in said pipe and connected at one end with said cone, said end being provided with a series of holes,:a valve upon said cone for closing the same, a delivery-tube at the other end' of the cylinder provided with a valve, and an ejecting-cone projecting into the free end of the main cone, substantially as set forth.

8. In an injector, the combination, with the casing, of an outlet-pipe connected therewith, a cylinder located in said pipe provided atils inner end with a series of holes and a valve for closing the same, a delivery-tube connected with the outer end of said cylinder, and a valve thereon, substantially as set forth.

9. In an injector, the combination, with a casing, of an adjustable ejecting-cone having bearing therein provided with a partition, a series of ejeeting'tubes projecting therefrom, a series of water-apertures opening into the space between the latter, and a circumferential groove adapted for the reception of the packing, substantially as set forth.

10. In a steain injector, the combination, with the overflow-pipe and the steanrinlet passage-way opening therein, of a valve located therein provided with an inwardly-pro-- jecting apertured tube, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
